hi friends, these days i trying to build myself a tune for this car, its my own car and trying to learn a petrol possibility
setup is this:

110kw stock AEB  - USA model - 557P - m5.9.2 ecu with am29f200
K04 turbo
S4 injectors 349cc
vr6 maf + housing 70mm
petrol regulator 4bar
pump in tank bosch 0580254040 - 6,5bar
large intercooler from audi 2.5tdi

make some edits and pulls, car sometimes run in high rpm okay but at low rpm is a problem, yerk happening about 3000 to high and etc..
i have stock narrowband, it says that in high rpm about 0.88v its too rich,think..on idle i have various AFR 1sec 0.15v, 1sec 0.6v, 1 sec 0.4 .. dont know what happening ..
also on idle maf reading about 2.0 to 2.5g/s, on peak read about 140g/s..
i tried on stock maf, its reading on idle 2.8g/s on peak 175-180g/s and have dtc after run - signal too high ( for maf )

thank you in advance, i can pay its not a problem for some hint and better results, maybe im wrong in choosing map to edit, which map i should base for this setup ?
thankssssss

Start with and OEM file tweaked for a VR6 MAF linearization vector and injectors/FPR latency values, minimum pulse and fuel injection constat to obtain proper load/MAF/Injection pulse values including STFT no more than -3% to +3% aprox and you will have a nice start with car from idle and low loads. It is very important that you setup LOAD constant precisly to achive LOAD window properly based with a bigger MAF if not whole car work will be crazy and all time get off maps.

Someone please? Thanks
